BOBBIN-HOLDER FOR SPINDLES OF SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 665,384, dated January1, 1901-.

Application filed .Tune 18, 1900. Serial No. 20,623. (Model.)

To all whom t may concern:

Be it known that I, JAMES S. DEELEY, a citizen of the United States, anda resident of Oaryville, in the county of Norfolk and State ofMassachusetts, have invented a certain new and useful Bobbin-Holder forSpindles of Spinning-Machines, of which the following is aspecification, reference being had therein to the accompanying drawings.

The invention relates to bobbin-holders more particularly adapted foruse in connection with spindles of spinning-machines; and it has for itsobject to provide a simple, efcient, and durable means for holding thebobbin firmly and rigidly in its perpendicular position upon thespindle. No packing is necessary to hold the bobbin upon the spindle;neither is it necessary to hammer the bobbin down upon the same to keepit in its proper position when my fastening device is used. Otherobjectsand advantages of my invention will appear` in the hereinafter-detaileddescription.

The invention consists, broadly, of metal lic spring-arms rigidlyattached to the spindle and extending outwardly thereform and upwardlyto receive and hold the bobbin, in combination with auxiliary springs.The invention also consists in providing the inner faces of the saidspring-arms with corrugations for the purposes hereinafter stated; andit further consists of the novel features of construction hereinafterset forth and described, and more particularly pointed out in the claimshereto appended.

Referring to the drawings, Figure 1 is an elevation of the spindle,bobbin, and holder. Fig. 2 is an elevation at right angles to that shownin Fig. 1, partly broken away. Fig. 3 is a plan of the upper washer andspring, with spindle in section. Fig. l is a plan view of the lowerwasher and spring, and Fig. 5 is a central transverse section taken onthe line 5 5 of Fig. 4.

Like letters of reference refer to like parts throughout the severalviews.

A denotes the spindle; B, the bobbin; O, the head of the bobbin, and Dan annular groove in the same.

d r1. are spring-arms extending outwardly and upwardly from the spindleand so curved and arranged that they'will flt into the arrnular grooveD, as shown in the drawings, Fig. l when the bobbin has been forced downbetween them to the desired point.

h l) denote the auxiliary or reinforcing springs, the outer ends ofwhich support the' arms a' d.

The spring-arms a d and the auxiliary springs b h are preferably made ofone piece of metal, the springs b b being formed by bending the metal ofthe spring-arms back upon itself until they come in contact with andtouch the said arms a d. The metal used is prefe'rably brass wireprovided with corrugations c c, running lengthwise with the wire and onthe inner side thereof, and in practice I find that three in number aresufficient for my purposes.

The springarms d d and the auxiliary springs b b iit into grooves orrentering angles d d, cut in the washer e, which may be called the lowerwasher. These parts are rigidly attached to the spindle A by drivingthem down or swaging them upon the coneshaped spindle until the desiredpoint is reached.

f is a second washer, which may preferably be called the upper Washer,which is likewise driven down upon or swaged upon the spindle to holdthe spring-arms and auxiliary springs firm and fast to the spindle. Theupper surface of this washerf may be provided with spurs or teeth g gfor clutching or biting the under side of the bobbin-head.

It is to be particularly noted that the auxiliary springs b b do notmerely double the strength of the springs of the spring-arms a a, butthey reinforce the same and by their joint action prevent the spreadingof the arms d a, for without the auxiliary springs, even if the grippingforce of the springarms were doubled, the spring-arms would after alittle use spread, thus causing the bobbin to slip and make it necessaryto use packing to keep it rigid on the spindle. The use of the auxiliarysprings prevents this spreading absolutely, no matter how long thebobbin-holder is used, and makes a holder the gripping force of whichpractically suffers no depreciation by use. Again, by this constructionone can set the springs far enough under the bobbin-head IOO so that theholder will hold a bobbin with a head a quarter of an inch smaller thanwill a holder with a single springthat is to say, if there be put on abobbin with a head large enough to open a single spring a quarter, of aninch it will spread the spring of the holder so much that it will notcome back -to its original position, and when it is put onto thesameholder it will slip, thus making it necessary to use a bobbiu with ahead much larger (about a quarter of an inch larger) than the one rstused; but this is not the case when the auxiliary springs are used, forthey tend to and do force the upper springs back to their originalposition, no matter if the samesized bobbin is used over and over again.

The corrugations c c on the inside of the spring-arms a a grip upon theside of the bobl bin-head when the bobbin is forced down be-` tween thearms and will make a place for themselves on the side of thebobbin-head,` thereby giving the arms a firmer hold on the? same than ifthey were made of smooth wire or metal.

The mode of operation of the device in so far as it has not already beendisclosed is asv follows: To place the bobbin on the holder, the bobbinis forced down between the springarms a a, thus causing the `springs b bto beV slightly compressed and the inner corrugated sides of said armsto grip the sides of theA bobbin-head, the upper part of said arms to;vit slightly into the annular groove D, and thei teeth g g to clutch orbite the under side of` the bobbin-head. It will be found after this1has taken place that it will be impossible to; turn or twist the bobbinin the holder. Tof release the bobbin,it is only necessary to press itgently underneath until it is forced upwardly by the force of thesprings, the auxiliary springs causing the spring-arms ct a to` resumetheir normal and original position.

lVhat I claim, and desire to secure'by Letters Patent, is

l. A bobbin-holder, comprisinga spindle or other like device incombination with springarms and auxiliary springs acting upon saidspring-arms, substantially as and forthe pur-1 pose set forth.

2. A bobbin-holder, comprising a spindle or other like device incombination with two spring-arlns and an auxiliary spring for supportingeach of said arms, substantially as described.

3. Abobbin-holder, comprisinga spindle or other like device incombination with two spring-arms and an auxiliary spring for supportingeach ofsaid arms,each of said spring. arms with its supporting auxiliaryspring being made of one piece of metal, a part of which is bent backupon itself to form the auxiliary spring.

4. A bobbin-holder, comprisingaspindle or other like device incombination with springarms and auxiliary springs acting upon saidspring-arms, the inner faces of said springarms being provided withcorrugations, substantially as and for the purpose vset forth.

5. A bobbin-holder, com prisinga'spindle or other 4like device, incombination with springarms a ct, auxiliary springs l) b'applied to saidarms, and washer e mounted upon the yspindle and supporting` thespring-arms'and `their auxiliary springs.

6. Abobbin-'holdeigcoln'prisingaspindle or other like device, incombination with springarms a a, auxiliary springs b b applied to saidarms, washer e mounted upon the spindle and carrying the spring-arms andauxiliary springs, and washer fapplied to the spindle and provided uponits upper surface with teeth, substantially'as described.

7. Abob'bin-holder, comprisingaspindle or other like device,bobbin-gripping arms applied to said spindle and adapted vto engage thebobbin, and a spring yacting upon said arms to insure theirgrippingaction, substantially as described.

S. A bobbin-holder, com'prisinga spindle or other like device, bobbingripping varms adapted to engage the bobbin and carry it around with thespindle, and a spring-support for said arms applied to the spindle,substantially as described.

KIn witness whereof Ihave hereunto affixed my signature, in the presenceof two witnesses, this 16th day'of June, 1900.
